FASTENER FOB STORM-WINDOWS AND'WINDOW-SCREENS.

Specification of Letters Patent.

Patented J an. 11, 1910.

Application filed September 28, 1909. Serial No. 519,960.

To all whom'it may concern:

Be it known that I, JOHN MICHAELSON, a citizen of the United States, and a resident of Peterson, in the county of Fillmore and State of Minnesota, have invented a new and Improved Fastener for Stormindows and lrVindow-Screens, of which the following is a full, clear, and exact description.

This invention relates to detachable means for removably securing a storm window in a window-casement, and in a like manner securing a window-screen therein, and has for its object to provide a novel, simple fastening device of the character indicated, which is convenient to apply to a windowcasement, and is adapted for reliably holding a storm window or a screen in place within a window-casement, on the inner side thereof, and permit the extra window or screen to be quickly detached from the window-casement when this is desired.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompany-- ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is an inner side View of a window casement, a storm window in lace thereat, and the improvement applie for securing the window removably in place;

Fig. 2 is a fragmentary perspective View of,

a window casement, a storm window sash and the improved fastening device adjusted for holding the sash locked upon the casement, and Fig. 3 is an enlarged sectional plan view of a portion of a window casement, a like view of a lower window sash, a storm window in part, and a plan view of the improvement mounted on the easement and engaging the sash of the storm window.

In localities where the climate is severe during the winter season, and cold winds prevail, the ordinary window sashes for a window are not suflicient protectlon, and it is customary to provide other sashes suitably glazed, that fit closely in the window casement and serve to close the crevices ordinarily formed around the outer window sashes, due to their shrinkage and also'that of the window casement.

It is essential for convenience in the manipulation of the sashes proper to open and close them, that the applied storm protecting window be adapted for quick and convenient removal from the easement, and to this end I have provided the improved sash-securing means that constitutes the invention, which will be described.

In the drawings that show the construction and application of the improvement, 5, 5, 5, 5 indicate the four members of a window casement, 6 a lower sash slidably secured thereon and 7 a storm window sash, that is neatly fitted into the completed casement 5. It will be noted in Fig. 3 that the edge of the frame for the stormwindow engages the corresponding edge of the molding 5 of the window casement, which retains the lower sash 6 of the window in proper position, so that the joint a between said molding and the storm window sash 7, does not come opposite a like joint between the casement jamb and sash 6, this breaking of the joints serving to prevent an intrusion of air currents through the joint around the window sash 7.

The improved means for removably securing the storm Window sash 7 in place within the easement members 5 comprises four similar appliances, each constructed as follows: A bracket plate 8 is provided, that is in the form of a fiat metal planchet having a preferably rectangular contour and elongated form. At each end of the plate 8 a keeper flange 8 is formed thereon, said flanges being bent at a right. angle from the body of the bracket plate toward the same side thereof. As shown clearly in Fig. 2,-each flange 8 is rounded on its corners b, and at the transverse center of the bracket plate 8 a flat-bottomed recess 0 is formed in the free edge of each flange 8 A latch hook 9 is an important feature of the securing device, consisting of a plate metal strip forming a lever, preferably having parallel side edges, and a hook 9 formed on one end thereof, said hook having a lateral opening (Z therein, that is defined by parallel edges, the nose 6 of the hook being pointed edgewise, as shown in Fig. 2.

The hook lever 9 is pivoted upon the bracket plate 8 at the center of said plate,

the pivot g passing through a perforation in the hook body near the hook member 9 and thence through a spacing washer h into the bracket plate, wherein it is secured. The hook lever 9 is of such width and length, as will permit the body thereof to be seated in either recess 0, thereby holding the hook half of the window only. If the window member so that its nose 6 projects laterally, as shown in Fig. 2.

As before mentioned, four of the improved securing devices are employed for the retention of a storm window sash 7 in position within the window casement, seated upon the closed lower sash 6.

In Fig. 1 it will be seen that two bracket plates 8 are secured upon each side member of a window easement that is to receive a storm window sash 7, said bracket plates being positioned oppositely in pairs at a proper distance from the upper and lower transverse members 5 of the window casement. It will also be seen in Fig. 1 that the bracket plates 8 are so disposed that the hooks 9 thereon will have their noses c projected away from the inner edges of the molding strips 5 whereon said bracket plates are at tached, this occurring when the lever members 9 of the hooks 9 are rocked into depending positions and interlocked with the recesses c in the lower keeper flange 8 In arranging the securing means for service, a looped projection, preferably in the form of a screw eye 10, is inserted into an ecge portion of the sash frame 7, at points that will dispose them respectively opposite a hook member 9. Each hook member may now be engaged with a mating looped end of the screw eye that is disposed opposite it, and it is to be understood that the screw eyes 10 are projected such a distance with their looped portions disposed horizontally, that when the storm window is placed in position and the hooks 9 are positioned relatively as shown in Fig. 2 by dotted lines, said hooks may be caused to enter the ring eyes and pull thereon so as to secure the frame 7 in place when the lever members 9 are rocked downward and interlocked within the recess 0 in the lower keeper flanges 8 as shown in Fig. l.

Preferably a hand-hold ring 2' is secured ,on a cross bar 7" of the storm window sash 7, which enables the convenient handling of said sash when it 18 to be placed in position, as it will permit the sash 7 to be lifted into eaaeeo place and there held while the hooks 9 are receiving rocked adjustment for their interlocking engagement with the looped ends of the ring eyes 10.

It will be evident that the storm window may be quickly placed and secured in position, and be readily released and removed from the window casement when this is desired.

As hereinbefore stated, the improved securing means may be utilized for the convenient attachment of a window screen upon the inner side of a window casement. In this application of the invention, the window screen frame may be of a size that will cover the entire window, or be of such dimensions as will adapt itto screen the lower screen is large enough to cover the entire window, four securing appliances should be employed and disposed the same as shown for the storm window in Fig. 1. If the window screen is to cover the lower half of the window, it may be secured in place by using two of the securing devices, disposed oppositely, that are attached on the easement and engage two ring'eyes which project from the screen frame. In either construction for a screen, the frame thereof may be quickly attached to a window casement on the inner side thereof and readily removed, as may be desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination with a window casement, and a window sash therein, of a frame for a supplementary window or screen that engages the easement on its inner side, and securing means therefor, comprising rockable hooks mounted on the easement and looped projections on the inner frame that are engaged by said hooks.

2. The combination with a window casement, and window sashes therein, of a frame for a supplementary window or screen, that is inserted in the easement at its inner side, and securing means therefor, comprising a plurality of bracket plates mounted on the easement, rockable hooks on said bracket plates, and looped projections on the inner frame, that are detachably engaged by said hooks.

3. The combination with a window casement, and window sashes therein, of a frame for a supplementary window or screen, that is inserted in the easement at its inner side, and securing means comprising a plurality of bracket plates secured on the easement, each bracket plate having similar keeper flanges at its ends, said flanges each having a flat-bottomed recess therein, a hook for each bracket plate, having a lever member thereon that is pivoted near the hook on a respective bracket plate, and a screw eye for the purpose specified and at the other a 10 for each hook, inserted in an edge of the handle for engaging a recess. inner frame opposite a hook for engagement In testimony whereof I have signed my therewith. name to this specification in the presence of 4.
